Hello,
I'm currently setting up backup jobs for a PVE host. While the VMs work fine, I'm running into some trouble with an LXC. The jobs all fail with exit code 23 at this rsync command:
I have tried running this manually from the container and narrowed the issue down to the /dev, /proc and /sys directories:
The error log from the /sys directory is too long to post here, but boils down to a lot of the same errors on different files. Excerpt:
Any suggestions? This also happens with the "Suspend" backup option, by the way. A backup using a full stop of the system works. Here's the container config:
